3 Open Source Virtualization Software Solution

Virtualization is to refer as a technology it enable us to run multiple operating systems and applications on the same server at the same time. Virtualization create virtual rather than actual version of resources like server storage device, network ,an operating system where the framework divides the resource into one or more useable environments. It can also be understand as like hard drive partitioning, it create two separate hard drives.

The way of utilizing the technology changing day by day. Virtualization technology provide scalability, flexibility and offer cost saving. It reduced workload and faster work performance and make work automated. Some of the benefits by utilizing virtualization are.

KVM (Kernal Virtual Machine) is full virtualization solution. It is also known as Kernel-based Virtual Machine. It can be run on both Linux and Window guest. It allow various programs to utilize the hardware virtualization features of various processors and it supported Intel AMD processors. In late 2008 Linux vendor Red Hat acquired KVM developer and now Red Hat bases its enterprise virtualization server on the KVM hypervisor. KVM provide number of features to their user some of these are Qemu Monitor Protocol, Kernel Samepage Merging, Paravirtual timesource for KVM, Adding cpus on the fly, Adding pci devices on the fly, Communication channel between the host and guests and many more.

Xen is an open source virtualization software solution. It has empowered some of the largest clouds in production. The most famous users of Xen are Rackspace Public Cloud, Amazon Web Services, Aliyun and many hosting services used Xen software. It allow the integration flexibility, you can integrate it into number of cloud orchestration projects such like OpenStack. It supported multiple guest operating systems like Linux, Windows, NetBSD. The list of features provided by Xen are Supports multiple Cloud platforms, Provide Reliable technology with a solid track record, provide Scalability, Security, Flexibility, VM Migration and Multi-vendor support etc.

OpenVZ is an open source container-based virtualization for Linux. It provide cost effective virtual private servers. It create different number of secure Linux container by using single physical server and enable us to better server utilization and confirm that applications do not conflict. It provide native performance by providing the same services on separate host container. Every container can perform like a stand alone server, it can be rebooted independently and also provide root access. OpenVZ provide the separate IP address, memory, files,system libraries,processor and configuration files.
